Upgrade Linux kernel on Ubuntu 14.04.3 to Mainline v4.3.4-wily

Upgrade Ubuntu 14.04 LTS to the newest kernel just in case you want to play with later versions of Dockers or systemd on an LTS release.

DISCLAIMER – MESSING WITH THE KERNEL CAN BE BAD. RUN YOUR BACKUPS AND SNAPSHOTS AND DON’T PLAY WITH LIVE AMMO!

Step 1 – First check “kernel.ubuntu.com/~kernel-ppa/mainline” to find out the current mainline kernel. As I type this it is 4.3.4 but you may not want to copy and paste these as it has probably changed by the time you read this. It is software, right?
